Chapter 7, Problem 7PP
(Numerical) Using the srand() and rand() C++ library functions, fill an array of 1000 floating-point numbers with random numbers that have been scaled to the range 1 to 100. Then determine and display the number of random numbers having values between 1 and 50 and the number having values greater than 50. What do you expect the output counts to be?

(Use Python)
The function course_average should calculate and return the average of the three values pass to it.
The function main should ask the user to enter three grades and then pass these values to the course_average function. This function should also display a message to the user in the format below.
For example, if the user entered 100, 90 and 95 the message would be:The average of 100 , 90 and 95 is 95

Write a program that will do the following:
In main, declare an array of size 20 and name it "randomArray." Use the function in step 2 to fill the array. Use the function in step 3 to print the array.
Create a function that generates 20 random integers with a range of 1 to 10 and places them into an array. Re-cycle the functions from Lab 10 where appropriate.
Make this a function.
There will be two arguments in the parameter list of this function: an array and the size of the array.
Within the function and the function prototype name the array: intArray.
Within the function and the function prototype name the size of the array: size.
The data type of the function will be void since the array will be sent back through the parameter list.
Bring in the function that generates and returns a random number that you created from the previous module. Call that function from this within the loop that adds random numbers to the…

- (C++) Question: Write a function string middle(string str)that returns a string containing the middle character in str if the length of str is odd, or the two middle characters if the length is even. For example, middle("middle") returns "dd". I'm not getting the correct output. What am I doing incorrectly?arrow_forward(python) prov_vac_status() takes a 2-D list (similar to the database) and an integer representing the province ID. This function returns three values; (i) the total number of unvaccinated patients, (i) the total number of partially vaccinated patients, and (i) the total number of fully vaccinated patients hospitalized in this province during the entire period. Note that these numbers include both the icu and the non-icu patients. >>> res1, res2, res3 = prov_vac_status(database, 12) >>> print(f"{res1}, {res2}, {res3}") >>> 194, 14, 118 >>> print(prov_vac_status(database, 35)) >>> (402, 28, 202) >>> print(prov_vac_status(database, 81)) >>> (0, 0, 0)arrow_forward(C PROGRAMMING ONLY) 2.

In this program, let's try displaying all the odd numbers of our array, life, but with the use of functions! Instructions: In the code editor, you are provided with an array called, life. Furthermore, in the main(), a function call was made to the function displayOdd() where the array life was passed as well as the size of life which is 90.Your task is to declare and define the function displayOdd() which has the following details:Return type - voidName - displayOddParametersint* - an arrayint - the size of the arrayDescription - displays all the odd numbers found in the array passed, starting from the end.

- 1. (Functions with Loop and Branches) Write a C program that uses the function, PrintShampoo Instructions(), with int parameter numCycles, and void return type. If numCycles is less than 1, print "Too few.". Else If more than 4, print "Too many.". Else, print "N: Lather and rinse." for numCycles times, where N is the cycle number, followed by "Done.". End with a new line. [hint: use "for" loop from 1 to numCycles times to get desired display] Example output with input 0: Too few Example output with input 5: Too many Example output with input 4: 1: Lather and rinse. 2: Lather and rinse. 3: Lather and rinse. 4: Lather and rinse. Done. #include /* Your user-defined function goes here */ int main(void) { int user Cycles; scanf("%d", &userCycles); PrintShampoo Instructions (user Cycles); return 0; }arrow_forward(Python) Write a function that receives a string containing a 32-bit hexadecimal integer. The functionmust return the string’s integer value.arrow_forward(Adding Large Integers) | In C++, the largest int value is 2147483647. So, an integer larger than this cannot be stored and processed as an integer. Similarly, if the sum or product of two positive integers is greater than 2147483647, the result will be incorrect. One way to store and manipulate large integers is to store each individual digit of the number in an array. Write a program that inputs two positive integers of, at most, 20 digits and outputs the sum of the numbers. If the sum of the numbers has more than 20 digits, output the sum with the message The sum of the numbers overflows. Your program must, at least, contain a function to read and store a number into an array and another function to output the sum of the numbers.(Hint: Read numbers as strings and store the digits of the number in the reverse order.)arrow_forward
- 2. (Functions with C string parameters) Write a program in C that uses the function, MakeSentenceExcited() to replace any period (full stop or comma) with an exclamation point. If the input string is: I told my computer I needed a break. It replied "I am sorry, I'm not programmed for that function." The output will be: I told my computer I needed a break! It replied "I am sorry! I'm not programmed for that function!" Assign a string size of 200 or above. Use "fgets()" to take the string input. Don't forget to include the string header file. Hint: A very similar example 3 problem is given in the lab slide. Try to follow that example.arrow_forward(C PROGRAMMING ONLY) 7. Comparing Charactersby CodeChum Admin Most, if not all things have numeric values. That goes for characters too. In order to find out which character has a higher value, we have to compare them with each other and display the value of the higher character. Instructions: In the code editor, you are provided with a main() function that asks the user for 2 characters, passes these characters to a function call of the getHigherValue() function, and then prints out the ASCII value of the higher character.Your task is to implement the getHigherValue function which has the following details:Return type - intName - getHigherValueParameters - 2 characters to be comparedDescription - the ASCII value of the higher character.Hint: Comparing characters in C is just like comparing integers.DO NOT EDIT ANYTHING IN THE MAINInput 1. First character 2. Second character Output Enter first character: aEnter second character: hResult value = 104arrow_forward(IN PYTHON) Problem 2 Write a function count_8s(string) that performs the following actions: Receives a single parameter called string that we expect to be a string. If we receive something that is NOT a string, raise a TypeError with the message “Non-string input received.” Uses recursion to count the number of eights in the string. Use a string of length 0 as your base case. Otherwise, determine if the first character in string is “8” or not, and call count_8s() again with the rest of the string as an argument. Returns the number of eights found in the string. NOTE: You are not to use a while or for loop in your code.arrow_forward

Spell-it-out!by CodeChum Admin Are you intimidated with complicated words? Don't be! The trick is to break it down letter by letter! Let’s create a program that prints out the character in the array index indicated by the input integer. For example, if the array has 3 character elements, 'j', 'r', and 'd', and the inputted integer value is 1, then we print 'r' because 'r' is found at index 1. Instructions: In the code editor, you are provided with an array of characters (or a string).Your task is to ask the user for an integer input which represents the index and then print out the character of the string found at that index.Input 1. Index of the array Output Enter the index: 4rarrow_forward
